Be it known that I, WILLIAM H. Rim),

a citizen of the United States, and a re'sident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in C- sures for Containers, of which the following is a specification.

This invention relates to closures for containers, especiallybottles and jars provided and terrain locking projections in the form of lugs or t reads in the skirt by inpressing bothoi the engaging walls and in which the raw or free edge of,the upwardly bent portion is covered or protected.

A further object of the invention is the. provision of a catsup cap that is a cap 1n which the skirt or flange usually has a length substantially equal to the diameter of the cap and which flange is upwardly bent and in substantial contact with itself to form a double wall provided with suitable hold ing'means. t

A further object of the invention 1s the 35 provision ofan improved cap in which the flange is provided with an upwardly bent portion is ing and in close engagement with the ange thereby forming a double thicmew of wall in which'a. locking projection in the form of a continuous thread is located. r

In the accompanying drawinl ag showing embodiments of an invention, igure 1 1s a vertical section" t with lugs.

Fig. 2 shows a screw thread pap.

Figs. 3 and d show a cap with multiple threads.

Figs. 5 and 6 show caps of-difierent shape Figs. 7, 8 and 9 show other forms of cap. 10, 11 and 12 show one prom of r the caps. It the drawing, the cap comrough the cap provided as A by bending the skirt back upwardly on itself itself, and then extending itprises a top ,2, and a skirt or flange that pro ects downwardly. The skirt as shown s composed of a downwardly extended portion 4 that is bent to extend upward, as at 5, in engagement with the portion 4. Thereby is formed a double walled skirt. This double wall is pressed at intervals to form inwardly projecting lugs 6, Fig. 1. These lugs it will be seen have double walls in engagement, and therefore can strongly resist pressure when they are brought to engage threads on a jar neck. Instead of forming lugs in the double wall of the skirt, screw threads may be pressed in, and may extend frbm the lower edge upwardly for a considerable distance. In Fig. 2, a single continuous screw thread is shown, starting at 8 in the lower edge and running upward, whereby such ca P g provided wit being shown that start at foufplacesequall spaced apart on (the bottom edge,, and whic threads extend upwardly. This cap can screw on a container having four similar threads, or can engage a container provided with four lugs adapted to enter the thread grooveson the inner wall of the caps In the several views described, the cap is. shown as provided with an overhanging rim portion 12, formed by extending the top wall 2 outwardly, then bendin it back on ownwardly, to form the skirt. The up er free edge of the outer wall 4 is prefer-a ly brought adjacent this rim, so that it is covered and practically concealed, and can not en age the hand of the user in applying an re- I moving the closure, and is thus protected from rust. 1 I

In Fig. 5 I show a closure with the shrt about as long asthe diameter of the to which caps are generally hown in t e trade as catsup caps and are'provided' with screw threads for about one-half of the skirt portion. It will be seen this cap, comprises a to 13 with a downwardly extending shrt 14 that is bent outwardly and u wardly to rovide an outer shrt wall'15. is could 105 extended to the topsimilar to Fig. Q,

with screw threads 3 for the extent of its height. In Fig. 6 a similar construction of catsup cap is shown, with the raw edge l8 l0 pressed inwardly into a groove 19 in the skirt to conceal the raw edge. It will he seen that the screw thread extends upwardly from the hottom edge and is composed entirely or doubled contacting walls.

In Figs. 7 and 8 I show another form in which the top 20 has a skirt 21 that is hent upwardly to form a wall 22, and this latter wall has the upper edge hent over inwardly to form a head 23. This double wall skirt formed hy-portions 21, and 22 is provided with lugs or screw threads 24 such as shown in Figs. 1 and 2, hut the outer wall does till not extend upward to the to hut has its raw edge protecte formed thereon.

In Fig. 9, ll show another form 0t cap comprising a top wall 30 having a skirt 31 hent over inwardly and extending upwardly in engagement with the outer wall, and the free or raw edge is at the upper portion near the top, where it would he en agedhy the liner. This douhle skirt wa l s impressed to form screw threads 35%which screw threads extend to the bottom of the cap."

in Figs. l0, l1, and 12,11 show one'process of forming this kind of closure when the flange is not too deep. The flat hlank 25 may he pressed into a hat shaped form, as shown in Fig. 11, with the skirt 26 having a portion 27 projecting outwardly, and a rim portion 28 at the top. The portion 2'8" is hent upwardly against the skirt wall 26; and the rim 28 is ressed outwardly as indicated in Fig. 12. en making a cap having a deep flange, such as a catsu cap, this style of cap may he made in any 0 the well-known ways,

hy the head the flange of course heing cut of sucient I de th to provide for the upturned portion.

ince the skirt is formed of two walls in-' stead of one wall, it can he constructed or lighter material, that is, of thinner sheet metal; and the doubled rim portion l2 also serves to reinforce the I cap at this place. This structure will eliminate the employment or any headed raw edge, as the raw; edge of the skirt is located at the upper part or the outer wall and heneath the overhanging rim; or heneath the head on the skirt.
